You can login to the router and setup WEP or WPA security, just make sure you really understand the procedure on your router or else you will lock out everyone including your own computer. Some linksys routers have a web-based setup section and putting in 192.168.2.1 will get you to those screens. Others require you to use the accompanying CD that came with the router. I have both kinds at the school where I manage the network. You can also use that web interface to see who is logged on and using your router. Read the manual or go to the linksys website and see the exact procedures for WEP or WPA security setup for your particular model.

i emailed customer rep as to what i can do and they are not replying...

im on 192.168.1.1 but i cant see who is logged on using my router? where can i see that info?

Sounds like you created an admin password to be able to get into the router settings, which is good so that someone who might be sponging off you can't get in and grant themselves access; however, you must also go into the security settings of the wireless section and enable WEP or WPA and give that another key or password depending on which of the two you choose. WPA is very secure but not as easily configured on your mac itself, whereas WEP is easy to come up with a 10 digit numeric key (64 bit) but can be circumvented if your neighbor has a sniffer program. We use 64 bit WEP at school since it is compatible with every type hardware we have (even older types). I first setup WPA here at home, but remembered my iPaq PPC and one of my old IBM Wifi cards didn't support it so I swithced to WEP and haven't had anyone sneak in. The monitoring section is under the section showing current DHCP leases.

Ok i totally did EXACTLY what the website told me to and it locked me out of my own internet connection! then i had to reset my router and luckily that reset the password to default

Once you set it up, you have to go into your own Mac airport settings on your mac and turn on that security. Essentially you click the airport signal at top of the bar up by the clock/speaker, choose your router from the list, and use the drop-down to pick the security type and enter the password.

Linksys router have good security controls once logged in to the router.

As already mentioned you should setup WEP or WPA security, (WEP is crackable within hours WPA is not).

Next thing you might want to do is restrict access to your router by MAC address - basically every computer has a MAC address, so you can identify the MAC address of your computer, key that in to the router's security section on "restrict access to".

But do setup WEP or WPA security because it IS possible to spoof a MAC address.
